What Happened

NFX General Partner James Currier defines a category called Enterprise Gateway Marketplaces (EGMs) — two-sided marketplaces that sit between large corporations (demand) and thousands of small external vendors (supply). Unlike traditional B2B marketplaces, EGMs embed directly inside enterprise systems, getting pre-approved by IT, legal, compliance, and finance. This makes it easier for employees to transact with outside vendors without triggering slow internal procurement processes. Examples include Candex, Guild Education, Salesforce AppExchange, and Scientist.com.

Why It Matters

Large corporations are structurally inefficient at buying from small vendors. The approval layers, compliance requirements, and contract overhead make it nearly impossible for small suppliers to reach enterprise buyers — and frustrating for enterprise employees who want access to better tools and services. EGMs solve this by acting as a pre-approved, trusted layer between both sides. The deeper signal: the same gig-economy flexibility that transformed how SMBs operate is now becoming available to Fortune 500s — but only through marketplaces that solve compliance and workflow, not just matching. This is a structural shift in how large organizations source external capacity, and it opens a significant white space for marketplace founders who understand how to build a marketplace and are willing to absorb that complexity upfront.

Marketplace Insight

Supply: Small vendors gain access to enterprise buyers they could never reach through direct sales. The marketplace qualifies and onboards them, reducing the cost and friction of enterprise selling. This is a powerful supply acquisition lever — vendors join because the demand is otherwise inaccessible.


Demand: Enterprise demand is fragmented across three internal stakeholders — executives, compliance gatekeepers, and end-user employees. Each has different needs. Executives want control and cost reduction. Gatekeepers want compliance. Employees want flexibility and speed. A marketplace that satisfies all three simultaneously unlocks the entire account, not just a single buyer.


Liquidity: EGMs solve the chicken-and-egg problem differently. Landing one large enterprise can immediately generate hundreds or thousands of internal buyers — enough to attract and justify supply. The first enterprise deal is effectively a liquidity unlock, not just a revenue event.


Trust: Trust in EGMs is institutional, not just transactional. Getting pre-approved by IT, legal, and finance IS the trust infrastructure. For supply, the marketplace curates and surfaces vendor data to reduce friction. For demand, the embedded compliance layer removes the need to re-evaluate vendors each time.


Growth: Growth inside an EGM is not just acquiring new enterprises — it's expanding within existing ones. The 'second sale' (spreading across departments and geographies inside one company) is the real growth engine. Network effects emerge when usage data from one division improves outcomes for another.


Onboarding: Onboarding has two distinct phases. Phase one: getting enterprise-wide approval (slow, relationship-driven, compliance-heavy). Phase two: driving adoption among employees (fast, UX-driven, bottom-up). Founders must build for both, and a solid marketplace launch strategy guide can help teams prepare for both phases before they arise. Failing the second phase after winning the first is a common and costly mistake.


Monetization: EGM revenue is tied to transaction volume, not just seat licenses. This means monetization scales with usage, not just with new logos. The implication: customer success and expansion inside accounts is directly tied to revenue growth, making it a core function — not a support function.

What This Means for Marketplace Founders

If you are building a B2B marketplace and your target customers include large organizations, the EGM model changes how you think about your go-to-market, your product, and your defensibility.


First, selling to an enterprise is not a single sale. You need buy-in from executives, compliance teams, and end users — three separate value propositions, three separate conversations. Non-technical founders often underestimate the compliance layer. Getting pre-approved by IT, legal, and finance is not a blocker to work around — it is the product feature that justifies your existence to executives.


Second, your defensibility comes from being embedded, not from being better. Once you are inside an enterprise's workflow and approved vendor list, the cost of replacing you is enormous. This is stronger moat than a better UI or lower take rate.


Third, your first enterprise customer should be treated as a market-maker, not just a revenue source. If they represent 500 internal buyers, that is enough demand to recruit serious supply. Use that anchor to build liquidity, then use supply depth to attract the next enterprise.


Finally, the 'land and expand' motion is not a sales strategy — it is your primary growth model. Founders who treat expansion as an afterthought will see stagnant revenue even with a growing customer list, and those who pair it with broader community marketplace growth strategies often find compounding momentum that purely transactional approaches miss.

Actionable Takeaways

• Map your three demand-side stakeholders before building: executive sponsors, compliance gatekeepers, and end-user employees. Build a separate value proposition and onboarding path for each.


• Treat compliance as a product feature, not a sales obstacle. Getting pre-approved by IT, legal, and finance reduces friction for every future transaction on the platform — it is your trust infrastructure.


• Use your first enterprise customer as a supply acquisition tool. One large account can represent hundreds of internal buyers — enough to attract vendors who would otherwise ignore you.


• Design for team usage from day one. Build in notifications, referrals, and shared workflows that encourage spread across departments without requiring a new top-down sale.


• Build a 'second sale' playbook. Define what success looks like inside one account at 30, 90, and 180 days post-launch. Assign responsibility for expansion, not just acquisition.


• Prioritize UX as a compliance strategy. Enterprise adoption is increasingly bottom-up. If employees don't find your product useful and easy, they won't use it — regardless of executive approval.


• Aim to be the complete vertical solution in your category. Breadth of supply reduces the incentive for buyers or sellers to use a competing platform, which directly limits multi-tenanting and churn.
